Blood gets its color from the presence of oxegenated iron.
due to the presence of haemoglobin
Blood is always red.
Oxygenated blood is red. The presence of carbon dioxide in the blood does not alter the color.
The blood of a lizard is typically red, just like the blood of other vertebrates. The red color comes from the presence of hemoglobin, a protein that carries oxygen in the blood.
Hematuria
Blood appears red due to the presence of red blood cells, which contain a protein called hemoglobin that binds to oxygen and gives blood its red color. The yellow color of plasma is due to the presence of proteins and fats in the liquid component of blood. When combined with the red blood cells, the overall color of blood appears red.
The villi in the small intestine are typically a pinkish color due to the presence of blood vessels.

Your blood type is determined by the presence or absence of certain antigens (proteins) on the surface of your red blood cells. The ABO system determines your blood type based on the presence of A and B antigens, while the Rh system determines the positive or negative factor based on the presence of the Rh factor (or antigen D). These antigens are inherited from your parents through their genes.
Urine has a yellow color due to the presence of urobilin, a product of the breakdown of red blood cells. The intensity of the yellow color can also be affected by hydration levels and the concentration of waste products in the urine.
The most common test used to determine if a stain is blood is the Hemastix test. This test involves using a strip of paper coated with a chemical that changes color in the presence of blood. If the stain contains blood, the paper will turn green due to the presence of hemoglobin.
The color of a snail's blood can vary depending on the species. In general, snail blood is typically a pale yellowish or greenish color. This is due to the presence of the green pigment chlorocruorin, which helps transport oxygen in their blood.
